Ranging Method, Radar, and Vehicle-Mounted Radar

An apparatus comprising:

• one or more processors;
• and
• a non-transitory storage medium coupled to the one or more processors and configured to store program instructions, wherein, when executed by the one or more processors, the program instructions cause the apparatus to:
• determine a first amplitude value set based on a first echo signal corresponding to a first pixel, wherein the first amplitude value set comprises first amplitude values corresponding to a plurality of first sampling points of the first echo signal;
• determine a plurality of second amplitude value sets based on the first amplitude value set and a plurality of second pixels in an associated area of the first pixel, wherein at least one of the second pixels is adjacent to the first pixel, wherein the second pixels are in a one-to-one correspondence with a plurality of second echo signals, wherein the second amplitude value sets comprise second amplitude values corresponding to a plurality of second sampling points of one of the second echo signals, and wherein second locations of the second sampling points are the same as first locations of the first sampling points;
• performing a first summation on the first amplitude values and the second amplitude values to obtain an accumulated amplitude value set for ranging on the target object.

A vehicle-mounted radar comprising:

• a laser configured to transmit a plurality of detection signals to reflect off of a target object to create optical signals;
• a detector configured to receive the optical signals;
• and
• a signal processing and control processor coupled to the laser and the detector and configured to:
• perform processing based on the optical signals to generate a first echo signal corresponding to a first pixel and a plurality of second echo signals;
• determine, based on the first echo signal, a first amplitude value set comprising first amplitude values corresponding to a plurality of first sampling points of the first echo signal;
• determine a plurality of second amplitude value sets based on the first amplitude value set and a plurality of second pixels in an associated area of the first pixel, wherein at least one of the second pixels is adjacent to the first pixel, wherein the second pixels are in a one-to-one correspondence with the second echo signals, wherein the second amplitude value sets comprise second amplitude values corresponding to a plurality of second sampling points of one of the second echo signals, and wherein second locations of the second sampling points are the same as first locations of the first sampling points;
• and
• perform a first summation on the first amplitude values and the second amplitude values to obtain an accumulated amplitude value set for ranging on the target object.
